Postcode Coordinate Applications

The Postcode Coordinates data is ideal for relating Postcodes and address information to their geographic location or to check if a postcode is still valid, or formatted within your database correctly. The data is therefore essential for analysing:

• The distribution of customers, suppliers or other address-based assets
• The most efficient routes and networks
• Addresses with respect to other geographic features
• Address locations with respect to geographical risks such as flood plains
• Validating postcodes you hold

• Full Postcode e.g. AB1 OAA
• Postcode Sector e.g. AB1 0
• Postcode District e.g. AB1
• Postcode Area e.g. AB
• PQI Position Quality Indicator
• X Coordinate Grid Reference e.g. 38536
• Y Coordinate Grid Reference e.g. 801193
• Longitude e.g. -2.242851
• Latitude e.g. 57.101474
• Date Postcode Introduced
• Date Postcode Retired (if applicable)

Coverage

The Postcode Coordinates data covers the United Kingdom (England, Scotland, Wales and Northern Ireland).

Grid References:

The majority of grid references are derived from the Ordnance Survey product OS MasterMap that contains grid references for each address. Newly introduced postcodes initially have a grid reference that has been imputed by ONS Geography. In due course these are replaced by improved OS MasterMap grid references which use data supplied by Ordnance Survey’s field surveyors.  The grid references provided for Northern Ireland postcodes are derived from the LPS ‘Pointer’ product and use the Irish National Grid system that covers all of Ireland and is independent of the British National Grid. These are then converted to the British National Grid system to ensure consistency across all Postcode records in the file.
